Abstract

Improvements in electronic control devices for the service of an injection installation of an internal combustion engine, of the type that comprises at least one injection valve, opens in a sequence synchronized with the revolutions of the crankshaft by means of a rectangular impulse and is kept open for a period of time determined by the control device depending on at least one parameter of the combustion engine, especially by the pressure in the suction tube, characterized in that said devices comprise a graduated time member from 5 to about 30 seconds, preferably up to about 25 seconds, which acts during this time on the duration of the pulse in the extension direction and which is switched on during the starting process.
